WILLIAM SIMMONS JUDD, OF GARTHAGE, MISSOURK BAND-CUTTER AND FEEDER FORTHRASHING-MACHINESF SPECIFICATION forming part of Letters Patent No.315,948, dated April 14, 1885.

Application filed December 22, 1884. (No model 1 To all whom it mayconcern.-

Be it known that I, W'ILLIAM S. J UDD, a citizen of the United States,and a resident of Carthage, in the county of Jasper and State ofMissouri, have invented certain new and useful Improvements inBand-Cutters and'Feeders for Thrashing-lllachines; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertainsto make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inwhich Figurelis a plan view of myimproved feeding and band-cuttin gattachment for thrashingmachincs. Fig. 2is abottom view of the same.Fig. 3 is a longitudinal vertical sectional view taken on the line wasin Fig. 1. Fig. 4 is a side view of the device. Fig. 5 is a transversesectional view taken on the line y 3 in Fig. l, and Fig. 6 is a detailview in perspective of the dctachable central guide-board and theadjoining parts.

The same letters refer to the same parts in all the figures.

This invention relates to band-cutters an feeders fort-hrashingmachines; and it consists in certain improvements in theconstruction of the same, having for their object to provide a devicewhich shall possess superior advantages in point of simplicity,durability, and general etiiciency, which may be readily andconveniently operated by connecting it with driving parts of an ordinarythrashing-machine, which shall be provided with swinging orreciprocating band-cutting knives, oscillating spreaders, and flexiblesheaf-guides, anda detachable center guide-board enabling the machine tofeed loose as well as bound grain, and having means for regulating thespeed and governing the motion of the various parts of the attachment.

YVit-h these ends in view theinvcntion comprises the construction andarrangement of parts, which will be hereinafter fully described, andparticulaily pointed out in the claims.

In the drawings hereto annexed, A designates the frame of the device,which consists of a bottom, 13, connecting the side beams, G C, therear-ends of which are provided with upwardly-extending sides orflanges, D D.

| E E are inclined guideboards secured pivotally to the side beams ofthe frame,near the front end of the same, and provided at their rearends with guides FF, embracing the side beams, and connected under thebottom of the device by a spring, G, serving to force the inner or rearends of the said guide-boards in an inward direction toward each other.

H designates a detachable center board, which is provided at its frontend with lugs I I, adapted to enter openings J in a transverse beam, K,connecting the side flanges of the device. The rear lower end of thesaid center board is provided with hooks L L, adapted to extend throughslots M M in the rear beam, N, of the device, which is provided on itsunder side with turn-buttons O 0, adapted to engage the said hooks, andthereby secure the said center board in position. \Vhen sheaves are fedto the machine, it is proposed to use the said center board, on eachside of which a'sheat' may be fed, and when loose grain is fed the saidcenter board is removcd.-

P and Q designate shafts, journaled transversely under the frame, at thefront and rear ends, respectively, and the latter of which is providedwith a conepulley, R, connected by a belt or band, S, with a conicalpulley, T, upon a central transverse shaft, U.

V designates a bell-crank lever, pivoted at V, and having a projectingarm, X, serving as a handle, by means of which a belt-shifter, Y,pivoted to the end of the other arm of the said bell cranklever may beadjusted. By this means the belt S may be adjusted, and

the speed of the device regulated.

One end of the shaft U is provided with a sliding clutch collar orsleeve, Z, adapted to be operated by means of a suitable lever, A,

whereby it may be thrown into or out of engagement with a handy-heel, B,upon the shaft U, whereby the device is operated.

When the clutch is in gear, this lever may be retained by a spring latchor catch, 0, and when the lever is lifted out of this latch asuitably-arranged spring serves to pull its other end so as to throw theclutchsleeve operated thereby out of gear.

The other end of the shaft U is provided with an eccentric disk orcrank, D, connected by a rod or pitman, E, with a crank, F, on one endof a shaft, G, mounted transversely .upon the upper part of the frame,and to which an oscillatory or rocking motion is thus imparted. Saidshaft is provided with cranks H H, with a pair of levers, I and J, oneof O O, and the sleeve K carries a plate, 1?, to-

which is pivoted a pair of fingers or stirrers, Q, formed in a singlepiece, and with a rearward-extending lug, It, under which fits acam-plate, S, pivoted upon the plate P, and which may be withdrawn so asto permit the said fingers to be raised or lifted out of the way. \Vhenthus raised or lifted, the lug R passes through a slot, T, formed in theplate P, and retained by swinging the cam-plate over it. It will beobserved that by the mechanism described the fingers O" and Q are os-'cillated in opposite directions, thus serving effectively for spreadingthe most tangled grain. When the grain is less tangled, thefingers Q maybe raised out of the way, as described.

The shaft U is provided with a pair of downwardly-extending curvedknives or cutters, which, as the said shaft oscillates, serve to cut thebands of the sheaves.

The ends of the shafts P and Q are provided with flanged pulleys U, onwhic-h run the belts V of the carrier, which is constructed simply oftransverse slats WV, connecting the said belts, as shown.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood. It is simple in construction, and may be readilyattached to any thrashing-machine of ordinary construction. It willoperate with equal efficiency for the purpose of feeding either loose orbound grain, the center board being readily detached for the formerpurpose. The bandcutters are simple and durable, and the spreadingmechanism is likewise simple, and are readily adapted to the peculiarrequirements of the grain which is to be fed. The flexible sideguide-boards will under all circumstances guide the grain in the properdirection and avoid choking. The speed of the machine may be easily andsatisfactorily regulated, and the machine may be instantaneously throwninto or out of gear, as may be required.

It is obvious that in the practical manufacture of this invention it maybe found desirable or necessary to make various slight changes in theconstruction and arrangement of details. I would therefore have itunderstood that I do not limit myself to the precise constructionhereinshown and described, but reserve to myself the right to all such changesand modifications as may be resorted to without departing fromthe'spirit of my invention.

Having thus described my invention, I claim and desire tosecure byLetters Patent of the United States 1. In a band-cutter and feeder forthrashingmachines, the combination, with the frame, of the pivotedinclined side guide-boards, the guards at the rear ends of the sameextending around the side beams of the frame, and a coiled springconnecting the said guards under the frame, substantially as and for thepurpose herein set forth.

2. In a band-cutter and feeder for thrashingmachines, the combination,with the inclined side guide-boards pivoted at the front end of theframe and connected flexibly at their rear ends bya spring arrangedunder the frame, of a detachable vertical center board, substantially asand for the purposes herein shown and specified.

3. In aband-cutter and feeder for thrashingmachines, the combination ofthe frame, the inclined swinging side guide-boards connected fiexibl yat their rear ends, and the transverselyarranged rock-shaft carrying thecurved knives or band-cutters, substantially as and for the purposeherein set forth.

4.. In a-band-eutter and feeder for thrashingmachines, the combination,with the frame, a transverse operating-shaft, and suitable connectingmechanism, of a vertical tubular shaft, a slotted plate provided withhinged spreading-fingers constructed with a rearwardly-extending lug, apivoted cam-disk, a vertical shaft mounted in the said tubular shaft,and a plate at the lower end of said shaft provided with permanentstirring-fingers, as and for the purpose shown and set forth.

5. The herein-described improvement in feeders and band-cutters forthrashing-machines, comprising the frame, the feeder, the inclinedswinging and flexible side guide" boards, the detachable center board, aspeedregulating device, spreadingfingers, mechanism whereby the upperones may be raised out of action, bandcutting knives, operatingmechanism, and mechanism for throwing the latter into or out of gear,substantially as and for the purpose herein shown and specified,

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses. I
